>gnl|CDD|162990 TIGR02733, desat_CrtD, C-3',4' desaturase CrtD. Members of this family are slr1293, a carotenoid biosynthesis protein which was shown to be the C-3',4' desaturase (CrtD) of myxoxanthophyll biosynthesis in Synechocystis sp. strain PCC 6803, and close homologs (presumed to be functionally equivalent) from other cyanobacteria, where myxoxanthophyll biosynthesis is either known or expected. This enzyme can act on neurosporene and so presumably catalyzes the first step that is committed to myxoxanthophyll. Length = 492

 Score = 38.5 bits (90), Expect = 0.003
 Identities = 16/31 (51%), Positives = 21/31 (67%)
